A small engine tachometer is a great piece of equipment to use when you need to keep track of the hours or RPMs of a motor. Most small engines do not come with a stock hours meter or tachometer. This can lead to premature failure of your motor if proper maintenance is not performed according to the hours that the engine runs.
Most engine tachometers can be purchased either online or in a specialty small engine store. Typical tachometers for small engines display the rotations per minute of the motor and the amount of hours the engine has been run. Almost all tachometers for lawn mowers and other small engines are self powered by a lithium ion battery made to last up to 35,000 hours. The tachometer has a spark sensor cable that is to be wrapped around the spark plug cable. This wire will sense the electrical signal that is sent to the spark plug to provide power for ignition of gas.
When installing a tachometer onto a lawn mower, boat motor or other small motor it is very important to install the tachometer into a safe place on the device where the possibility of damage is minimized. Although the majority of hours meters are water sealed it is important to attempt to keep water from getting onto the meter to prolong the life of the unit. Most hours meters / tachometers will last years if they are properly kept for.
Configuring the tachometer is dependent on the manufactures directions. Key information that you would need to configure the tachometer is:
Engine type, 2 or 4 stroke
Number of cylinders the motor is equipped with
Concluding, a small engine tachometer can be a great tool to use to keep the motor on the boat, lawn mower or other small device up to date with service. The hours meter will allow you to properly and correctly perform preventative maintenance.
